Application filed February 28, 1905. Serial No. 247,658.

To all w/wm, it may concern.-

Be it known that I, Onns'rnn OoMs'rocK, a citizen of the United States, residing in borough of Brooklyn, city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.

This invention is directed to the art of lubricating, and comprehends the admixture of a fluid, whether said fluid be a lubricant or not, with a non-liquid lubricant, whereby the lubricating substance may be conveyed to the parts to be lubricated when those parts are under pressure.

The invention further comprehends the construction of a device or apparatus which will automatically accomplish such admixture and feed it by a gradual discharge to the parts to be lubricated with a degree of efficiency and Y simplicity that will render it practical and desirable.

It is a further design of the invention to provide means for deflecting the course of the flow of the fluid as it is directed toward the non-liquid lubricating-substance and for thereafter directing it along a surface of the said lubricating substance whether that surface be within or without that body.

It will be understood that the device shown may be used in a variety of ways, as will be shown in the specification.

The constructions illustrated on the accompanying sheet of drawings, together with the detailed description thereto appertaining, disclose one of the forms into which the invention may be embodied.

An embodiment of the invention is illustrated on the accompanying sheets of drawings, Whereon Figure 1 is an elevational view of an improved lubricating apparatus associated with a steam-chest. Fig. 2 is a sectional view in elevation of the same. Fig. 3 is a perspective View of a lubricant-conveying member. Fig. i is a plan sectional view on line a a of Fig. 2, and Fig. 5 illustrates a lubricating device associated with a cylinder.

Throughout the various illustrations similar characters of reference apply to similar parts.

As has been remarked, that inasmuch as the principle of this invention-that is, the conducting of a fluid to a non-liquid lubricant, then discharging them in a compound stateis capable of being embodied in a variety of devices I have, for example, illustrated a device applied to a feed-pipe, for instance, as shown in Fig. 1, and to a cylinder in another instance, as shown in Fig. 5. In either case it will be observed that the invention primarily comprehends the provision of a reservoir adapted to contain a fluid whether a lubricant or not, a receptacle for containing non-liquid lubricant, means for introducing the fluid into contact with non-liquid lubricant, means to deflect and thereafter direct the flow of the fluid relatively to the non-liquid lubricant, and means whereby may be ascertained the amount of lubricant used.

Referring now to the construction as shown, 6 indicates in a general way a reservoir, which may be made in any suitable manner and which in the present instance may be mounted upon a support 7, having a portion 8, which may be screw-threaded internally, as at 9, so that it may be fitted onto a cup 10, which may be externally screwthreade :l at 11 to receive the screw-threaded portion 9 of said support.

Suitably associated with the chest 10 is a valve 60, provided with a valve-plug 12 and which may be screw-threaded at 13, so that it may connect to a leader-pipe 14, if desired, or to the body of a cylinder 15, Fig. 5.

Within the chest 10 may be located a cup 16, having an opening 17 at its upper portion and which cup may be stepped into a seat 18 in the base of the chest 10. This cup is designed to hold some suitable lubricating substance 19-such, for instance, as graphite or graphite compounded with another suitable lubricating mediumsuch, for instance, as soap, preferably soft soap. The former may be used if the reservoir 6 is to be filled with oil for use with air-compressors and gases, and the latter may be employed if said reservoir is to be filled with water for use with steam-cylinders, in which latter case the soap will serve as a vehicle to establish an aiiinity between the water and graphite. \Vithin this cup may be located a member which may COID- prise a base 20, having a standard 21, from which may extend in an oblique and upward direction a deflecting-plate 22, and mounted also upon the base 20 is a support 23, which in the present instance may be provided with a screen 2a, which maybe constructed of some suitable open-mesh material, such as gauze or wire-netting. This material 24 will be disposed sufiiciently distant from the member 23 so as to create a space or channel 25 between the screen 24 and the member 23, and thus when the structure is placed in the cup and the lubricating mass is surrounding the same said lubricating mass will be held a certain distance away from the member 23, so as not to choke or obstruct the channel 25.

It is designed that communication may be had between the chest and the interior of the reservoir 6 for the purpose of directing into the cup a pressure of any suitable medium which may be directed into the chest 10 through a port 26, passing through the wall 27 of a support 28, upon which the cup 16 may be disposed, and this port 26 communicates with the valve 60, by which the pressure of the medium may be controlled. These communications may be of any suitable form and in the present instance are illustrated as for ready removal.

tubes 29 and 30, which are perpendicularly disposed within said reservoir 6 and which pass through the bottom 31 of said cups and through the support 7 into the chest 10, and such tubes are designed to extend to an approximate point relatively to the top of the reservoir 6, which in the present instance may be inclosed by a cap 32, screw-threaded, for instance, as at 33, to the interior of the cup and which may be milled, if desired, as at 34, This cap in the present instance may be provided with a bearing 35, through the bore of which may extend a stem 36, and the bearing 35 may be screw-threaded exteriorly, as at 37, to accommodate the cap 38, which may be screw-threaded to correspond with said screw-thread 37 and between this cap and the hearing may be confined suitable packing 39 for preventing the escapement of the pressure in the reservoir 6. The shank 40 of the stem 36 may be screw-threaded, as at 41, and pointed, as at 42, and may be movable in an internally-screw-threaded valve 43, which may be screw-threaded into or otherwise situated at 44 in the bottom of the reservoir 6, and this valve may be provided with a nozzle 45, having a channel 46, which may connect with ports 47, leading into the chamber 6, and the point 42 on the shank 40 of the stem 45 may operate as a needle-valve plug to control the communication between the ports 47 and the channel 46, and for the purpose of manipulating the valve-stem the same may be provided with a knurled head 48.

The valve just referred to is preferably located just above the opening 17 of the cup 16, and the nozzle thereof may be directed into the glass tube 49, which may enter the chest 10 and by which the amount of flow of a liquid lubricant 50, contained in the reservoir 6, to the cup 16 may be ascertained.

When the pressure of a medium is permitted to enter through the port 26 into the chamber 10 and the same passes through the tubes or channels 29 and 30, there will be a pressure in the lubricating apparatus equal to that of the pressure emanating from the mechanism adapted to be lubricated.

The liquid, which may be regulated to any desired flow, will be expelled from the nozzle of the valve and drop upon the deflecting portion 22 of the member 21 within the cup 16, whereupon it will run upon the mass of the non-liquid lubricant and will spread over the same, and when it reaches the wire-cloth 24 it will trickle down said cloth and into the channel 51, passing through the support 28, where it may drip off drop by drop through the valve to the parts to be lubricated, it being understood that as the fluid 5O spreads over the non-liquid lubricant each drop thereof may carry with it a portion or deposit of the lubricant by a process of erosion, whereby the product which passes through the channel 51 will be the composition of the substance in the chamber 6 and the substance in the cup 16.

As has been remarked, the substance from the chamber 6 leaves the nozzle 45 in drops 52, which drops pass through the glass tube 49, and in this Way the speed with which the lubricant is being fed to another can be ascertained by the rapidity with which these drops are being expelled from the nozzle. It

will also be observed that by causing the liquid from the chamber 6 to be deposited upon the deflecting-surface 22 of the member within the cup 16 the drops emanating from the nozzle of the valve will not wear the non-liquid lubricant in one spot, so as to cause a puddle of the liquid, which would be a detracting feature in carrying out the erosing process.

For the purpose of preventing back-pressure against the flow of the lubricant to the parts to be lubricated when the pressure of a medium is first introduced into the apparatus 1 may locate the channel 51 in the portion 28 somewhat within the caliber of the conduit in the valve, so that the valve-plug 12 may be partially turned for the purpose of giving communication between the source of supply and the chamber 10 and yet at such partial turning will prevent the medium from entering the channel 51. Then the pressure has been circulated throughout the device, when the valve-plug 12 may be fully opened, when the channel 51 may communicate with the conduit of the valve.

The use of various characters of lubricants is comprehended, among which may be those which may comprehend the use of graphite lying in a mass within one receptacle and oil contained in another receptacle and being imparted to and upon the surface of the mass, preferably through intermittent discharges that is, drop by drop-when the oil while traveling upon and around the surface of the mass may bya process of erosion take up particles of the graphite and carry them along with itself to the parts to be lubricated, whereby there is discharged to such parts a compounded lubricant comprehending the admixture of oil and graphite.

If desired, from the chamber 6may emanate water, possibly most practically obtainable by condensation (if steam be used as a medium or pressure) or which may be placed into the cup if another medium or pressure be used, and the graphite in the cup 16 may be compounded with a suitable proportion of any suitable substance which may operate as a vehicle to create an affinity between the Water and the graphite. In this connection it is here remarked that such vehicle, if desired, may, and probably in practice will, consist of soft soap admixed with the graphite in a manner in accordance with the subject-matter of my pending application, filed February 28, 1905, Serial No. 247,659.

It will now be observed that I have provided a lubricating device for discharging a lubricant or fluid and combining it with another lubricant by an intermitted process and whereby the two lubricantsare directed to the place to be lubricated in a compound or mixed condition. It will be further observed that I have provided a method by which to determine the amount of lubricant being utilized, also for controlling the amount to be utilized. It will be further observed that I provide a device which may be located within the mass of one of the lubricants whereby the lubricant conducted thereto may be properly and eiflciently directed in order to give efficient results.

It will be noted that the introduction as a lubricant of oil into the graphite is not essential, it being understood that the graphite alone being a lubricant may be carried to the parts to be lubricated by such other suitable medium as may be selected.

Within the purview of this invention I may resort to various constructions or assemblage of parts of lubricating apparatus so long as I maintain the integrity of the principle of combining two or more lubricants, a fluid with a non-liquid lubricant, and effecting such combination through means whereby both will be carried to the parts to be lubricated.
